Be yfitr: known that 1 FRANK' J TYrANsnI,

a/.citizenl'of the UnitedStates, residing 'at Detroit, in thecou-ntyo-.f--layne and'fState' of Michigan, have invented a new and use.Lv

ful. Improvement in Windowv Ghair, of which the followingpis aspecifica-tion.

Myfinvention: relates tola new and useful improvement in a window chairand has for its object the provision of a chair adaptable for attachmentto the sill vof -a window so that the operator in washing the window maybe seated comfortably and safely in the chair.

Another object of the invention is the provision in a chair of thisclass of means for attaching the chair to window sills of varyingwidths.

Another object of the invention is the provision in al chair of theclass mentioned of a movable engaging member having sup-k portingmembers co-operating with guide members mounted on the base of the chairseat. n v

Other objects will appear hereinafter.

The invention consists in the combination and arrangements of partshereinafter dcscribed and claimed.

The invention will be best understood by a reference to the accompanyingdrawings which form a part of this specification.

Fig. 1 is a perspective view of the invention attached to a window,

Fig. 2 is a bottom pla-n view of the invention,

Fig. 3 is a sectional view taken substantially on line 33 of Fig. 2,and,

Fig. 4 is a sectional view taken substantially on line 4-4 of Fig. 2.

The invention isadapted to afford a chair for customary use in thehousehold and at the same time to provide a scaffolding which may beattached to a. window sill for use when the windows are being washed.The size and dimensions of the chair may vary depending upon the tasteof the one using IApplication filed yNovember19;, 1923. l Se'riaI'NO.675,496. v i i t' at the forwardv end thereof with a crank`12 andeafcollar 13 which 'is adapted to'engage against the surface of the'cross 'member 14 joining the legs 10.- F iaedly` y[mounted on the rod11, adjacent one end thereoffis a coll-ar 1413Hwhich is kadapted#tolengage' one side of a cross member 16 which joins the legs 9. Theother side thereof being engaged by collar 15, loosely mounted upon therod 11 and retained in place by a cotterpin y or other suitableattaching means. Mounted on the rod 11 isa nut 17, which extendstransversely of the rod 11, and is attached at its ends to slidebars 18,each of which is provided at it-s upper end with a T 19 and at its lowerend with a pair of wings 22 and 22', which are attached in any suitablemanner to a movable engaging member or crossarm 24, which is provided onone face with a yielding covering such as felt 24. The Ts 19 slidablyengage in guide members 20 and 20 which are mounted on the under surfaceof the seat 5. One edge of the members 20 land 20 rests in closeengagement with the under surface of the seat 5, while the other edgethereof is offset to provide a space between the members 20 and 20 andthe seat 5 in which the T 19 may engage for slidable movement. Themembers 20 and 20 are spaced apart from each other to provide a space inwhich a member 18 may ride.

In operation the chair is placed over the window sill so that the member9 may engage against the outer surface of the window sill or the outersurface of the wall directly beneath the window sill. The crank 12 isthen turned until the member 24 is brought into close engagement withthe inner surface of the wall or the window sill. In this way thechairis clamped in position on the window, so that the party washing thewindows may sit in the chair in safety and comfort. In this manner abackward toppling of the window washer from the window sill isprevented, the cross member 8 serving as a suitable support. It is to benoted that, the screw arrangement kwhereby the clamping members aremovedinto oper.- ative and inoperative position permits the use of thesaine chair on windows of different widths. Another feature of theinvention is the mounting of the clamping members directly beneath theseat of the chair so that they are invisible when the chair is used fordomestic purposes.

"While I have illustrated and described the preferred form ofconstruction, I do not wish to limit myself to the precise details ofstructure set forth, but desire to avail inyself of suoli variations andmodifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is:

In a chair of the class described, a stationary engaging member mountedbeneath the seat of said chair; pairs of oppositely disposed spacedguide members mounted on the undersurface of said chair and havingfacing edges thereof spaced from the under surface of said chair; a pairof movable arms, each being provided with a T adapted for riding in thespace between said guide members and said undersurface, and engaging aportion of the upper surface of said guide members; a clamping membermounted on said arms; a nut mounted on said arms; a threaded rodprojected through said nut and adapted to effect movement of said nutlongitudinally of said rod for moving said arms relatively to saidstationary engaging member, said rod being supported for rotatablemovement beneath the seat of said chair.

In testimony whereof I `have signed the foregoing.
